1. in order to save this file, you must save it with a different name. you will get these 2 warnings, in order: "do you want to save these changes?", "make sure the path and filename are correct". click ok to both.

2. save "DefaultInput.ini" as "aDefaultInput.ini".

3. you will notice that you now have both "DefaultInput.ini" and "aDefaultInput.ini". delete "DefaultInput.ini".

4. rename "aDefaultInput.ini" to "DefaultInput.ini"

5. pat yourself on the back, youve completed the hardest parts.

PART 3 - changing the keybindings in-game:

1. once in a game, go to the controls, and change any bindings that have been reset, which now conflict with your new action key.

in my case, this involved switching flares from "F" to something besides "F".
